OIL BURNER.

Applicationfiled March 1, 1924. Serial No. 696,263.

To all whom it may concern:

Be it known that I, JAMns- F.'SUTTER- FIELD, a citizen of the United States, resid-' ing at Goose Creek, in the county of Harris and State of Texas, have invented-certain new and useful Improvements Bu1-ners,'of which the following is a specification, reference being hadto the accomin Oil panying drawings. r

I This invention relates to an improved oil burner of the vaporizer type and one object of the invention is to provide an oil burner which is provided with improved vaporizer means and which includes oil containing 'pockets'so that when the burner isjinitially placed in operation thevpockets may contain a reserve supply'of oil which will be con- I verted into gas after the vaporizer has beenheated by oil. burning in the oil pan and will" 20' supply gas which will be ignited and will burn for some time, thereby making it imnecessary for the operator to watch the burner when it is initially lighted and turn the oil on as soon as the oil in the pan has been consumed.

Another object of the invention is to so construct this burner that the flame from theburning gas may be directed towards certain of the reservoir pockets and actj'in a very eflectlve manner to convert this 're- I serve supply of oil into a gas.

construct this burner, that one of the reser-- voir forming pipes may be extended to a point close to the pan sothat this pocketmay be thoroughly heated by a burning oil,

" construct this burner that the flame spread' er may be suspended about the outlet nozzle by means of a yoke suspended from pipes" forming the side arms of the vaporizer Vpartiallyinverticalsection.

Another ob'ect of the invention is to so wick placed in the pan and saturated with Another object of the Another object of the invention-is to so portion of the burner.

This invention 1S illustrated in the accompanying drawings, wherein g I a Figure 1 is a'view showing the improved a burner, principally in side elevation and" and extends beyond this'coupling-15 to' a invention is to soconstruct this oil burner that the pipe linemay be formed of ordinary pipe sections: connected by couplings and thepockets forthe reserve oil also formed of pipe sections connected with the pipes forming the vapor-'- izer portionof the burner by couplings.

Figure 2 is-a top plan view of the improved burner with the flame spreader left off.

I Figure 3 1s a view showing the flame spreader in side elevation and suspended from the side pipes of the vaporizer, the side pipesbeing shown insection.

Figure 4 is a longitudinal vertical sectional view through the burner.

Figure 5 is a view in side elevation showing a construction having two of the burners provided above a pan.

Figure 6 is a top plan View of the pan shown in-Figure 3.

This burner is provided with a pan 1 which will be preferably rectangular in shape and provided with the usual side and end flan'ges or walls so that oil may be placed in this panin order to initially heat the pipes forming the vaporizer of the burner. At one corner the pan is provided with an elevated platform forming portion 2 which is of sufficient height to prevent the oilin the pan from flowing over this platform. This platform is provided with an opening through which extends a coupling 3 which serves to connect the burner with a supply pipe 4; leading to a tank 5 in which the supply of oil will be kept. This supply pipe tmay be provided with a valve 6 adjaoent'the tank 5 and with a second valve 7' adjacent its connection with the coupling 3 soathat this valve 7 may be easily reached when operating the burner. I

The burner is provided with a "substane tially- U-shaped'vaporizer forming portion which is positioned in spaced relationabove the pan 1 and is provided with spaced side arms 8 and 9 which, are formed of pipes and are connected with dependin pipes 10 and 11 by suitable couplings 12. I hepipe 11 extends downwardly and is connectedwith the 7 coupling 3 sothat this pipe 11 communicates; with the'supply pipe 4:. The pipe 10 has its lower'end connected with a pipe 13'. by means of a coupling 14: of the elbow type and this pipe 13 extends along the pan 1 and terminates intermediate the length and width of the pan. A coupling 15 is connected with thispipe 13 and extends upwardly and has connected with its upperrend a short point adjacent the other end of the pan. Each of the pipes 8 and 9 is formed of end sections which are connected by a T coupling 19 and these T couplings 19 are provided with depending arms which carry short pipe sections 20 closed at their lower ends by caps 21 and forming pockets for receiving a reserve supply of oil. At the ends opposite the couplings 12 the pipes 8 and 9 carry couplings or elbows 22 and between these couplings 22 there has been provided a T coupling 23 connected with the couplings 22 by short nipples 24. This coupling 23 is also provided with a depending arm with which is connected a pipe 25. This pipe 25 which extends downwardly from the coupling 23 also forms a pocket for receiving a supply of oil. It should be noted, however, that this pipe 25 is of greater length than the pipes 20 and is of such length that the cap 26 which closes its lower end will be positioned very close to the extended end portion of the wick 18. Therefore, when the wick is saturated with oil and this oil is ignited the burning oil will thoroughly heat the pipe 25 and also thoroughly heat the pipe 13 and coupling 15 and nozzle carrying pipe 16.

The oil in the pipe 25 will therefore be expanded and a portion of this oil will flow through the vaporizer and supply oil to the pipe 13. When the gas is generated it is desired to have the flame deflected and, there fore, there has been provided a flame spreading disc 27 which is positioned above the nozzle 17 and suspended from a yoke 28, the ends of which rest upon the pipes 8 and 9. This deflector will cause the flame to be spread so that the flame will serve to thoroughly heat the pipes 8 and 9 and also heat the pipes 20 forming the depending oil receiving pockets.

When this improved burner is in use it will be set up as shown with the pipe 1 leading from the oil supply tank and connected with the coupling 3 at the lower end of the pipe 11. The an may be positioned in the fire box of a cook stove or at any other point where it is desired to make use of the device. The valve 7 may then be opened and a sufficient quantity of oil permitted to pass through the pipes to cause a portion of the oil to flow out of the nozzle 17 and into the pan to soak the wick and if necessary provide a certain amount of unabsorbed oil in the pan. By having the wick formed of asbestos the oil may be burned without the wick being consumed. As the oil flows through the pipes forming the burner the pipes 20 and 25 will also be filled so that a reserve supply of oil will be provided. A match will then be applied to the wick so that the oil will be ignited and as this oil burns it will thoroughly heat the pipe 13 and pipe 25. The heatln of the pipe 25 will cause the oil contained in this pipe to be expanded and as this oil expands it will flow into the pipe 8 and down the pipe 10 into the pipe 13 so that additional oil is fed to the pipe 13 and will be converted into gas which will pass out through the nozzle 17 and become ignited. This gas will be directed upwardly as it passes through the nozzle and when ignited the flame will strike the disc 27 and will be deflected so that the pipes 20 and 8 and 9 and also the pipe 25 will be thoroughly heated by the burning gas. The oil in the pipes 20 and 25 will therefore be caused to give off a gas which will pass through the pipes 8, 10 and 13 to the pipe 16 and out through the nozzle 17. In view of the fact that the pipes 20 and 25 carry a quantity of oil this oil will supply gas to the burner for a relatively long length of time. Therefore, the operator does not need to stay close to the burner when it is initially lighted so that he can be sure to turn the valve on as soon as the oil in the pan is consumed and then light the gas as it passes out through the nozzle. After he has lighted the oil in the pan he can leave the burner and as soon as the pipes 20 and 25 are heated a suflicient amount the oil in these pipes will be converted into gas which will be ignited from the burning oil in the pan. As soon as this gas is burning a roaring noise will be caused which will attract the attention of the operator and he can then open the valve 7 a sufficient amount to supply oil to the burner to take the place of the oil which is consumed. This oil passes through the pipes and is vaporized in passing through the pipes 8 and 9 so that it passes into the pipes 10 and 13 as a gas and then passes upwardly through the pipe 16 and through the outlet of the nozzle 17. It will therefore be seen that there has been provided an oil burner Which is very eflicient in operation and it can be very easily operated.

If it is desired to'construct this burner for use in large stoves or furnaces and the like the pan 1 may be made of a greater length and a platform 2 provided intermediate the length of the pan with a partition 29 extending from this platform to the other side of the pan. The pipe 4: could then be provided with branch pipes 30 and 31 leading from it to the couplings 3 of burners of a duplicate construction and provided With valves 7 and 7. It might also be constructed so that any number of these burners could be provided above a pan of suitable dimensions.
